Engineering Innovation
Our experts love a design challenge. We can provide products that conform to most market specifications including a wide range of catalogue items. Our design database includes more than 10,000 products.Our quality assurance program further complements our ability to deliver products on time with exceptional PPM performance.
Custom Configurations
We design and manufacture single and three phase transformers using all known soft magnetic materials, sheet steel (iron and nickel types), powdered metals, ferrites and amorphous metal. Custom configurations utilize unique mountings and terminations to fit diverse product requirements. Our designers will find the best solution based on performance, lead-time and cost.
Few manufacturers have the extensive range of capabilities and processes available at E Craftsmen for parts weighing less than .03 lbs (1g) to over 500 lbs.

Offshore Partnerships
E Craftsmen has long standing relationships with trusted vendors located in China, Taiwan and India and we can utilize these partners when higher volumes would suggest cost-reduction potential. We value our relationships with these vendors and have been working with some of them for upwards of 10 years. Each of these companies has their own unique competencies and we select the most suitable manufacturer based on the part parameters.
Any effort to utilize these partners is conducted in a way that is fully visible and trouble-free for our customers. Typically, all production parts are shipped to our facility in Waterloo, Ontario, for 100% conformance testing before delivery to our customer. In some cases, however, we can facilitate a drop-shipment program from our vendor directly to the customer’s own off-shore facility; of course, this scenario may require additional quality assurance provisions.
At E Craftsmen, we create powerful solutions that work … with guaranteed results. Contact us to discuss your requirements.
